Don Jr., President Trump's son, tests positive for Covid-19

President Donald Trump’s son, Don Jr., has tested positive for Covid-19, a spokesperson confirmed Friday.

Don Jr. tested positive at the beginning of the week, according to the spokesperson, and “has been quarantining out at his cabin since the result.”

“He’s been completely asymptomatic so far and is following all medically recommended Covid-19 guidelines,” the spokesperson said.

"My son Donald is doing very well. Thank you!" the president tweeted Saturday morning.

Don Jr. is the latest member of the Trump family to have tested positive for the disease. His girlfriend and top Trump campaign official Kimberly Guilfoyle tested positive for the virus over the 4th of July weekend in South Dakota.

President Trump tested positive in early October, resulting in a three-day stay at Walter Reed Medical Center. Both First Lady Melania Trump and Barron Trump, the president's son and Don Jr.'s half brother, also tested positive around the same time as the president.

White House staffers have also been affected by a number of Covid outbreaks, including Chief of Staff Mark Meadows earlier this month. Vice President Mike Pence's chief of staff, Marc Short, tested positive for the disease last month.

The White House has hosted a number of events that eschewed social distancing guidelines, including a crowded Election Night party that Don Jr. attended. Don Jr. also hosted a densely packed indoor campaign rally days after his father tested positive for the virus.

Speaking with Fox News' Laura Ingraham last month, Don Jr. downplayed the severity of the pandemic, saying "the number [of new deaths] is almost nothing because we have gotten control of this. We understand how it works."

More than 11 million people have been diagnosed with Covid-19 in the United States. More than 250,000 people in the country have died from the disease.

News of Don Jr.’s diagnosis also came on the day Andrew Giuliani, an aide to the president and the son of Trump’s personal attorney, Rudy Giuliani, tested positive for the virus.

The younger Giuliani attended a news conference with his father Thursday where the former New York City mayor and other members of Trump's legal team challenged the legitimacy of the 2020 election. Trump campaign lawyer Jenna Ellis tweeted Friday that she and Rudy Giuliani tested negative for the virus.

News of Don Jr’s diagnosis was first reported by Bloomberg.
